Request parameters

**Table 2** Request parameters
Parameter	Mandatory	Type	Description
template_name	Yes	String	Specifies the name of the custom alarm template. The name can contain 1 to 128 characters. Only letters, digits, underscores (_), and hyphens (-) are allowed.
template_description	No	String	Provides supplementary information about the custom alarm template. The description can contain 0 to 256 characters.
namespace	Yes	String	Specifies the resource type selected for creating the custom alarm template, that is, the service namespace. For example, if you select ECS, namespace is SYS.ECS. NOTICE: If you select OS monitoring, namespace must be SYS.ECS.
dimension_name	Yes	String	Specifies the dimension corresponding to the resource type. If ECS is selected, the ECS dimension and dimension_name are instance_id.
template_items	Yes	Arrays of objects	Specifies the alarm rules that you add to the custom alarm template. You can add up to 20 alarm rules.

**Table 3** **template_items** data structure description
Parameter	Mandatory	Type	Description
metric_name	Yes	String	Specifies the metric you add to the custom alarm template. For example, you can add ECS cpu_util. To view metrics of each resource, see Services Interconnected with Cloud Eye.
condition	Yes	Condition object	Specifies the alarm policy you created for the custom alarm template. For details, see Table 4.
alarm_level	No	Integer	Specifies the alarm severity. Possible severities are 1 (critical), 2 (major), 3 (minor), and 4 (informational).

**Table 4** **condition** data structure description
Parameter	Mandatory	Type	Description
comparison_operator	Yes	String	Specifies the operator of alarm thresholds, which can be >, =, <, >=, or <=.
count	Yes	Integer	Specifies the number of consecutive occurrence times that the alarm policy was met. Supported range: 1 to 5
filter	Yes	String	Specifies the data rollup method, which can be max, min, average, sum, or variance.
period	Yes	Integer	Specifies the period during which Cloud Eye determines whether to trigger an alarm. Unit: second Possible periods are 1, 300, 1200, 3600, 14400, and 86400. NOTE: If you set period to 1, Cloud Eye uses raw data to determine whether to trigger an alarm. You can set this parameter to 0 when you set alarm_type to (EVENT.SYS\| EVENT.CUSTOM).
unit	No	String	Specifies the data unit. Enter up to 32 characters.
value	Yes	Double	Specifies the alarm threshold, which ranges from 0 to Number. MAX_VALUE (1.7976931348623157e+108). For detailed thresholds, see the value range of each metric in Services Interconnected with Cloud Eye. For example, you can set ECS cpu_util to 80.
suppress_duration	No	Integer	Specifies the interval for triggering an alarm if the alarm persists. Possible intervals are as follows: 0: Cloud Eye triggers the alarm only once. 300: Cloud Eye triggers the alarm every 5 minutes. 600: Cloud Eye triggers the alarm every 10 minutes. 900: Cloud Eye triggers the alarm every 15 minutes. 1800: Cloud Eye triggers the alarm every 30 minutes. 3600: Cloud Eye triggers the alarm every 1 hour. 10800: Cloud Eye triggers the alarm every 3 hours. 21600: Cloud Eye triggers the alarm every 6 hours. 43200: Cloud Eye triggers the alarm every 12 hours. 86400: Cloud Eye triggers the alarm every day.
